Next, you’ll want to mark off the axes with just enough evenly spaced tick marks to accommodate the full set of data. Determine the range of data values for each axis.
(a) What is the largest value to go on the x-axis? What is a reasonable spacing for the tick marks, and what should be the highest one?
(b) What is the largest value to go on the y-axis? What is a reasonable spacing for the tick marks, and what should be the highest one?\

Regulation of isoleucine synthesis is an example of feedback inhibition of an anabolic pathway. With that in mind, explain how ATP might be involved in feedback inhibition of a catabolic pathway.

How would the processes of catabolism and anabolism relate to Figure 8.5c?

Which combination has more free energy: glutamic acid + ammonia + ATP or glutamine + ADP + $P_i$ ? Explain.

$$\text{\blue{WRITE ABOUT A THEME: ENERGY AND MATTER}}$$

Life requires energy. In a short essay (100–150 words), describe the basic principles of bioenergetics in an animal cell. How is the flow and transformation of energy different in a photosynthesizing cell? Include the role of ATP and enzymes in your discussion.
